undefined datebocks_field

Hello,
This issue came up on another thread, but there wasn't any solution. I
also posted in reponse to it but I guess it got buried as an old
thread...

I have datebocks installed and working great on my local machine, but
on dreamhost I get this undefined datebocks_field error, though I've
killed and
started new fcgi processes several times. I've triple checked
everything mentioned on the other thread: I have both the engines and the
datebocks_engine installed correctly, my environment config has
Engines.start :datebocks, and both ApplicationController and
ApplicationHelper include datebocks.

on my local machine I'm using Locomotive 2 (mongrel), and on
production I have the standard apache/lighttpd/fcgi setup, with Rails
1.1.6

one thing I noticed on development was that sometimes I would get this
same error when loading a view using datebocks for the first time
after starting the server, but from the first refresh on it would work
fine. perhaps this is related?

any help would be greatly appreciated, been stuck for a few days...
